i owned one of these style rides years ago, i did a 2 metre high jump made out of scrap wood and crates and over shot the landing!!, back end slammed so hard the seatpost,back end,spring all snapped, wheres health n safety when you need the anoying bastads...
haha i remember i rode one of em! (i was bikeless and anything would do) so i asked this kid if i could have a go and aww do not jump them!! they are terrible id rather run the trail honestly!
